Translation of the original operating manual
NOTE
The vacuum pump is supplied with power by the unit, but the maximum
current for the vacuum pump is limited. It is absolutely essential to refer to
the label of the electrical outlet for the vacuum pump (see the following
picture)!
If the current requirement of the vacuum pump is higher than the value
that is stated on the label, the pump must be supplied separately via an
on-site power socket.

The oil mist that escapes from the pump during operation must be retained
or discharged via an exhaust filter (oil mist separator).
• We strongly recommend using an oil mist separator. The filter prevents
air pollution by the oil mist that is emitted more or less strongly by the
pump depending on the working pressure.
• The exhaust gases must be discharged in a proper manner.
• The hose line must be laid in such a manner that any condensation
water cannot flow back into the pump. In the case of a rising hose line,
we recommend using a condensate trap (Woulff bottle or wash bottle).

Pressure control valve
The pressure control valve is integrated in the suction pipe between the
vacuum pump and ice condenser chamber. During certain, specified
process phases, it interrupts the volume flow to the vacuum pump (see
chapter 2.2.1 - "General information on freeze-drying")
CAUTION
The pressure control valve is integrated into the system. Only specialised
personnel is authorised to perform maintenance or repairs.
